| Popis: | Statement of the problem. The paper seeks to clarify the regulations of calculation of steel-reinforced concrete bridge superstructures based on the generalization of modern scientific achievements on par with the possibilities of computational software and computer technology in the field of calculations of multi-component sections without the need to use simplifying hypotheses that affect the accuracy of the calculation. Results. An algorithm for calculating continuous multi-span beams of bridge structures with the possibility of taking into account the flexibility of the shear joint between concrete and steel structural elements is proposed that increases the accuracy of determining the stress-strain state (SSS) of the structure. The results of the work can be used in the design of steel-concrete bridge superstructures. Conclusions. The significance of the work lies in the fact that the proposed analytical dependen-ces in the joint use of modern computing power will clarify the calculation of steel-concrete bridges, thereby increasing the level of reliability of bridge structures laid at the design stage. №1(45) (2020) |
